An authenticated UI/API user with Variable read permission could harvest plaintext secret values stored under sensitive keys nested deep enough to exceed the masker's depth cap. Affects deployments that store sensitive values inside deeply-nested JSON Variables. This is a residual gap in the fix for CVE-2026-32690 (which covered shallower nesting via `max_depth=1`); the depth-limit boundary itself was not raised, so the same key-name bypass pattern reappears beyond the recursion cap. Users who already upgraded for CVE-2026-32690 should additionally upgrade to `apache-airflow` 3.2.2 or later to cover the deep-nesting path."}, {"lang": "es", "value": "Un error en el enmascarador de respuesta de Variables de Apache Airflow caus\u00f3 que la redacci\u00f3n de claves anidadas (activada por nombres de clave con sufijo de secreto como 'password', 'token', 'secret', 'api_key') fuera eludida cuando la profundidad de anidamiento del valor JSON exced\u00eda el l\u00edmite de recursi\u00f3n del enmascarador de secretos compartidos: el enmascarador devolv\u00eda el elemento anidado original antes de verificar el nombre de la clave sensible.
